18 Claims. (Cl. 66-89) This invention relates to novel and improved mechanism for knitting fashioned fabrics such as full fashioned hosiery.

Heretofore in knitting full fashioned hosiery it has been customary to fashion or narrow the fabric by shifting or transferring loops at the fabric edges a distance of ,two needles. This has been considered desirable in order to produce a uniform selvage edge to facilitate subsequent seaming. K However, it has been found that this two needle movement often results in excessive stretching of the yarn with consequent weakening of the fabric. This two needle'movement also often results in bending of the narrowing points and needles, causing imperfect registration thereof and resulting in imperfect loop transfers and 1 frequent dropping of loops when subsequent narthe gummed condition of the fabric before the stocking is completed. As a result of the stretching of the yarn, stressing of the fabric andthe possibility of the occurrence of dropped loops,

' runners are apt to develop when the stocking is subjected to stretching when worn.

An object of the present invention is to obviate these disadvantages and in carrying out my invention I effect the fashioning by transferring the loops so that the yarn is not unduly stressed and the narrowing points and needles are not bent and misalined.

In the drawings:

Figure 1 is a side view of a stocking made in accordance with my invention;

Figure 2 is a fragmentary enlarged view of a flat knitted stocking blank and shows the manner of transferring the loops in carrying out my invention;

Figure 8 is an end view of certain parts of a well known full fashioned stocking knitting machine embodying improved mechanism for carrying out my invention; and

Figure 9 is a detail view of part of the mechanism. shown in Fig. 8. p

In accordance with my improved method of knitting the full fashioned stocking shown in Figure 1, the welt i is produced in well known manner on a full fashioned knitting machine. The leg part ii is also as heretofore except that in fashioning instead of moving all the transferred loops inwardly two needles at each edge of the fabric, as heretofore, the loops |2 (Fig. 2) transferred by the narrowing points are all moved inwardly a distance of one needle at each edge of the fabric, and part of thetransferred loops are then moved inwardly an additional distance of one needle at each edgeof the fabric.

I have diagrammatically illustrated one method of accomplishing narrowing according to my invention in Figures 3 to 7 which indicate a complete narrowing cycle and upon consideration of which my improved method will be readily understood by those skilled in the art. The numeral l3 designates the ordinary thread carrier rod used in laying the yarn to produce the fabric and l4, l are the end stops for rod l3, these stops being mounted on oppositely threaded portions of spindie l6 and operated on rotation of the latter. The

usual narrowing rods I8 have mounted thereon narrowing points 29 and are yieldingly held in engagement with the narrowing rod end stops 2|, 22 and 23, 24 respectively, by springs 25 and 26, these stops being operated by spindle 21. In Figs. 3 to 7, the dot-dash lines designated 9, 2, 4, 6 indicate carrier rod end stop positions separated by two needle spaces while the lines a, b, c, d, e designate positions for the narrowing rod end stops spaced by the distance between successive needles.

At the beginning of a narrowing operation, as shown in Fig. 3 the end stop It for the carrier rod I3 is positioned at the point 0 on spindle it it are moved down-' wardly in unison to cause narrowing points 29; to engage loops at a desired point of narrowing,

and are then raised and the narrowing and rod end stops 2|, 24 and 22, 23 moved inwardly. and outwardly, respectively, a distance of only one needle space, as indicated in Fig. 4 by the positioning of stops 2| and 23 at the points 0. Simultaneously with the movement of the narrowing rod end stops, carrier rod end stops It and are moved inwardly a distance of two needle spaces, as indicated by the alinement of stop It with the point 2 in Fig. 4. The carrier rod end stops remain inthis position throughout the subsequent stages of the narrowing cycle as indicated in Figs. 5 to 7.

The narrowing rods are lowered to transfer the shifted loops to needles spaced one needlespectively, a distance of at least two needles, as

indicated by the alinement of stops 2| and 23 with the points a Fig. 5, thereby moving the nar-' rowing points outwardly the same distance. Narrowing rods I1, I8 are again lowered to cause narrowing points 2 to engage only a few of the loops previously shifted and transferred. The narrowing rods are raised and the end stops 2|, 24 and 22, 23 are again moved, inwardly and outwardly respectively, a distance ,of only one needle space to the points b, as indicated in Fig. 6. The narrowing points are then lowered to transfer the shifted loops to the needles, the needles to which loops are transferred being in the specific embodiment illustrated in the drawings, a needle space inward of those from which the loops were taken. The narrowing rods are again raised and the end strops 2|, 24 and 22, 23 are preferably moved inwardly and outwardly, respectively, a distance equal to that of the foregoing outward movement of the narrowing points, which, in the embodiment shown, is a distance of two needle spaces to the points d, Fig. 7, so that narrowing rod end stops 2|,-24 are again in the same positions relative to carrier rod end stops I4, I5, as in Fig. 3 and the narrowing points 26 are properly positioned for a subsequent and similar narrowing operation.

In Figure 8 I have illustrated one form of mechanism which I have found suitable for operating the end stops for the thread carrier rod and the narrowing rods in accordance with my novel narrowing method as described above. A vertically reciprocable member 36 is connected to a rocker arm 3I which is operable by a cam 32 on the usual cam shaft 33 and by a spring 34, for effecting reciprocation of member 36. Member 36 carrles a pawl 35 biased by a spring into engagement with a ratchet 36 secured to thread carrier rod spindle I6. The part 310! member 36 is connected to the arm 36 of a bell crank rotatively mounted on narrowing rod spindle 21 for-causing a spring biased pawl 46 mounted on bell crank arm 4| to engage and operate a ratchet 42 fixed on spindle 21. Pawl 46 is provided with a hook 43 cooperating with a pin 44 on a support 45 for limiting the operation of ratchet 42 and spindle 21 by the pawl. Also mounted on member 36 is a pivoted pawl 46 for engaging a second ratchet 41 on spindle 21 to operate the latter reversely to its operation by pawl 46 and another pawl 43 engageable with ratchet 42 at a point opposite pawl 46. Pawl 48 is pivotally mounted on anextension 56 of pawl 46 Pawls 46 and 46 are movable into and out of operative relation with ratchets 41 .and 42, respectively, by means of a slide 5| having notches 52 and 63 provided with shoulders engaging studs 54 and 55 on the pawls for moving the latter. A spring 56 connected to slide 5| and stud 55 of pawl 46 biases the latter into engagement with ratchet 42. Slide 5| is supported by a link 51 pivotally connected thereto and to a member 56. Slide 5| is connected to and operable horizontally by a lever 66 pivoted intermediate its ends and having a roller engaging a Maltese cross-shaped cam 6| fixed to a stub shaft 62, A ratchet 63 secured to shaft 62 is intermittently operable by a pawl 64 mounted on repiprocating member 36, a single spring between lever 66 and pawl 64 maintaining the lever roller and the pawl engaged respectively with the Maltese cam and its associated ratchet. Lever 66 is also provided with a pawl lifter 66 for controlling the engagement of pawl 35 with ratchet 36 on carrier rod spindle I6.

As cam shaft 33 rotates, a segment 61 mounted at the side of a cam 63 operates a rocking arm 16 to intermittently advance a pattern chain 1| carrying buttons for controlling axial shifting of shaft 33 in well known manner to bring cams 32 and 13 into operating position when narrowing is to be effected. Cam 13 imparts motion to a rocking lever 12 for raising and lowering the narrowing rods I1, I8 and narrowing points 26 while cam 32 controls the reciprocation of member 36.

When cam 32 acts through rocker arm 3| to raise member 36, pawl 64 advances ratchet 63 to turn Maltese cam 6| a single step, an arm or raised portion of the cam moving lever 66 clockwlseagainst the force of spring 65. This movement of lever 66 frees pawl 35 from the restraint of pawl lifter 66 and shifts slide 5| to the right for moving pawl 46 into operative relation with ratchet 41 and pawl 46 away from engaging rela tion with ratchet 42.

As member 36 continues its upward movement pawl 35 acts through ratchet 36 to turn spindle I6 for moving carrier rod end stops I4, I5 inwardly two needle spaces while at the same time pawl 46 engaging ratchet 42 turns narrowing rod spindle 21. Pawl 35 moved by member 36 turns shaft I6'an amount corresponding to two needle spaces and although pawl 46 is moved a like amount by member 36 the hook 43 and pin 44 hold pawl 46 inactive during part of the movement. Consequently, ratchet 42 is operated to move the narrowing rod end stops 2|, 24 and 22, 23, inwardly and outwardly respectively, a distance of only one needle space so that narrowing points 26 are shifted one needle space inwardly.

When spring 34 acts to move member 36 downwardly, pawls 35 and 46 move reversely and idly over ratchets 36 and 42 but pawl 46, being engaged with ratchet 41, rotates spindle 21 in the reverse direction moving the narrowing rod end lowered to engage the fabric and raised to transfer the engaged loops, the upward movement of reclprocative member 36 by cam 32 causes pawl 64 to turri Maltese cam 6| another step alining a recessed portion between arms thereof with the roller on lever 66. Inasmuch as spring 65 acts to maintain the roller of lever 66 against cam 6| the lever is rocked counter-clockwise causing pawl lifter 66 to move pawl 35 away from ratchet 36 and moving slide 5| to the left thus disengaging pawl 46 from ratchet 41 and positioning the shoulder of notch 53 so that spring 5-6 maycause pawl 46 to engage ratchet 42.

During the continued upward movement of member 36, pawl 46 again turns spindle 21 to move narrowing rod end stops 2|, 24 and 22, 23, inwardly and outwardly respectively, a distance of one needle space. Pawl 35 is held by lifter 66 and is ineffective to turn shaft I6, and the carrier rod stops remain in their shifted position.

lit)

The narrowingrods l1, l8 and points 20 are lowered to transfer the shifted loops and then raised from the fabric and assprlng 34 moves member 30 downwardly pawl It acts to turn spindle 27 so that the narrowing rod end stops 2|,

' 24 and 22, 23 are shifted, inwardly and outwardly respectively, a distance of two needle spaces so that the narrowing points 20 are shifted inwardly two spaces and the narrowing rod end stops 2i-24 are again in the same relative positions to the carrier rod end stops l4, l5 'as in Fig. 3.

A narrowing cycle is now completed and normal courses are again knit until another narrowing operation is to be performed. In these normal courses the yarn or thread is laid on two fewer needles at'each side of the fabric than before thenarr'owing'took place. a

In the above described narrowing cycle the narrowing points are lowered to engage a number of fabric loops, then raised to take loops from the needles andon being shifted inwardly are again lowered-to transfer the loops to needles each separated by' one needle space from the needles from which the loops are taken. Consequently the innermost one A (Fig. 2) of the shifted loops is transferred to a needle already having a loop thereon. When the narrowing points are raised, shifted outwardly two needle spaces, lowered to engage the fabric and again raised, the narrowing points retain fewer. loops than in the previous loop transferring opera,-

to transfer the loops, the innermost loop B is transferredto a needle already having a shifted loop thereon, which needle, in the'illustrative form shown in the drawings, is immediately adjacent the other needle having a double loop, including loop A. Thus, as shown in Figs. 1 and 2, the "narrowing marks resulting from the shifting of loops in narrowing operations comprise two series which are in separate wales of the stocking.
